AUTOMOBILE PROTECTION DEVICE.

. Application filed. May 17,

To all whom it may cancer Be it known teat I, GEORGE ConnouRNn, acitizen of the United States, and a resident of Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful improvementin r'iutomobile Protective'Devices, of which thefollowing is a. specification.- v 1 My invention relates to automobilepro tective devices, and it has particular relation to devices forcontrolling the-supply of fuel for gas engines.

One object oi? my invention is to provide a protective device of suchcharacter as to effectually prevent unauthorized use of an automobile.

The second object of my invention is to provide an arrangement in whichtheyparts of the mechanism for rendering a gas engine operative andinoperative are removable and interchangeable whereby the engii' e-cannot be operated in the absence of one of the parts.

lflumerous devices heretofore for the purpose of preventing ti eunauthorized use or theft of automobiles. Such devices generallycomprise member which has two positions in one of which the enginerendered inoperative. Protective devices may, however, be adjusted totheir operative positions in case the lock is broken. The partsnecessary for the operation of the engine are not removed therefrom.

According to the present invention, I pro vide two independent,removable and interchangeable parts for controlling the manifold of agas engine. One of these parts or the vent shutter is provided with anopensize to that of the enother or blind shutter when it is substitutedit effectually prevents engine by obstructing nine manifold. The has noopening and for the first shutter, the operation of the the enginemanifold.

In the accompanying drawing, Fig. 1 is a side view in elevation, of thecarburetor and manifold of an automobile engine with my inventionapplied thereto.

Figs. 2 and 3 are respective side and end views of the shutter-case.

Fig. i is a view, partially in section and partially in elevation of theshutter-case and the vent shutters, the latter being partiallywithdrawn.

Figs. 5 and 6 are respectively side and edge views of the vent shutter.

have been proposed,

Fig. 7 is a side view of the solid or blind shutter.

Referring to the drawing, a manifold l of a usual gas engine isconnected to a carbu- 6 retor 2 of any suitable or usual type. Theopening or passageway for connecting; the carburetor to the manifold iscontrolled by a protective device 2 comprising; a shuttercase 3 'whichis inserted between the adjacent ends of the manifold and the carburetoroutlet. Each. of these associated parts is provided with laterallyextending flangese having suitable openings for the reception of bolts5. The bolts are provided with nuts 6, lock washers? and with pins8. ofhardened steel, for securely and permanently retaining the nuts 6 inoperative,position. The. pins 8 prevent the removalof the. nuts 6 in theabsenceof special tools for such purpose The shutter-case 3, shown indetail in Figs. 2, 3 and 4c, is provided with an opening 8 whichcorresponds in size to that of the carburetor outlet and the manifold.The device 3 is provided with a laterally extending slot 9 of wedgeshape for the reception of the one or the other of two shuttcrsnvhich'may be termed, respectively, the. vent shutter 10 and the blindshutter11. The vent shutter 10 is provided with an opening the diameter ofwhich corresponds to that of the opening' 8 and the openings in theassociated parts. The blind shutter 11 has no opening", and when it isin position, the open ing in the manifold is effectually closed. Each ofthe shutters provided with a hole. 13 by means of which padlock or othersuitable locking device may be inserted for the purpose of preventingits unauthorized removal.

The operation of my improved protective device will'be readilyunderstood from the foregoing description. When it is desired to operatethe car, the vent shutter 10 is inserted, as illustrated in Fig. 1, andisloclred in position by a padlock 14 to prevent the unauthorizedtamperin'g with, and the consequent disabling of, the machine. When theparts are assembled in the manner described,

the engine operates in the usual or normal remain in the m achine, butis retained in the possessionof the driver. sible for the machine to beoperated by any person except the driver without breaking the lock,removing the blind. shutter 11, and

closing the end portions of the slot 9. This procedure is difiicult ofexecution because all the parts are constructed of highly tempered andhardened steel.

It is practically impossible, also, to so close the openings or the slot9 as to render the mechanism operative. in addition, it will requireconsiderable time and the use of considerable force to destroy thelocking device and to take such StQ'JS as. are necessary to render themacliiin-e operative. The

danger of detection is so great that it is entirely unlikely that anattempt will be made to either use the machine without the authority ofthe owner or to attempt thethett of the same.

It will-be noted that'l providean arrangement in which the necessaryparts for the operation of the machine are entirely removed .from thelatter when it is desired to prevent its unauthorized use. I

A devlce constructed in accordance with my invention maybe manufacturedat low cost. It is of such nature that it may constitute a standard partof any and all automobiles. It may also be incorporated in the structureof automobiles at any t1 me during their operation. The above and otheradvantages will be apparent to those skilled in" the art to which myinvention appertains;

I claim as my invention: I

l. A protective device comprising a memher for conducting fluids havinga lateral opening and a pair of independent removable members thatcooperate with said opening to respectively permit only or preventonly'the passage of fluid through said con- "ducting member. saidremovable members be ing non-rotatable relatively to said conductingmember;

'2. A protective device comprising a memher for conducting fluids havinglateral opening and a pair of independent remov able members thatcooperate with said open ing torespeotivel'y permit only or to preventonly the passage of fluid through said con-' ductmg member, said membersbeing interchangeable.

A protective device comprising a mem= ber-' for conduct ng fluids havinga'lateral' opening" and a-pai'r of independent inter changeable"non-rotatableshutters that coop It is now impose being so arranged thatit may erate with said opening to respectively permit or prevent thepassage of fluid through said conducting member.

4. A protective device, comprising a memberior conducting fluids havinga lateral opening and ;a pair of independent removable members thatcooperate with said openlng to respectively permit only, or to' preventonly the passage of fluid through said conducting member, one of saidremovable mem- 5 bers'being so arranged that it may be locked inoperative position i 5.'A protective device comprising a memher forconducting fluids having a lateral opening and a pair of independentinterchangeable non-rotatable shutters that cooperate with said openingto respectively permit or prevent the passage of fluid through saidconducting member, one of said shutters be locked in operative position.

6. A protective device comprising an engine manifold having a pair oflateral open ings extending therethrough, a pair of independent andinterchangeable shutters removably associated with said openings forpermitting or preventing the passage of fuel through said manifoldaccording as the one or the other shutter is in position in saidopenings, said shutters being. nonrotatable with respect to saidmanifold.v

7. A protective device comprising an en movably associated with saidopenings for" respectively permitting "only "or preventing-J only thepassage of fuel through said manitold according as the one or the othershut ter is in position in said openings, one of saidshutters'having anopening whereby 1001; may be inserted. 1. 1
